  • Flow rate measurement device and flow rate measurement method
    Patent number: 10151610
    Abstract: A flow rate measurement device is configured to measure a flow rate of a gas flowing inside of a pipeline, and includes an ultrasonic transducer installed so as to be in contact with the pipeline, and a flow rate calculation part configured to calculate the flow rate of the gas according to a result of reception of ultrasonic wave from the ultrasonic transducer, wherein the ultrasonic transducer includes an ultrasonic oscillation part configured to emit the ultrasonic wave toward the inside of the pipeline and an ultrasonic reception part configured to receive the ultrasonic wave, and at least the ultrasonic oscillation part has a focusing part configured to focus the ultrasonic wave on a center of the pipeline.

  • FLOW SPEED MEASUREMENT METHOD AND FLOW SPEED MEASUREMENT SYSTEM
    Publication number: 20170184432
    Abstract: A flow speed measurement method includes conducting a heat exchange at a prescribed part of a surface of a pipe, the flow speed measurement method further includes measuring a temperature distribution in a pipe-axis-direction on the surface of the pipe in a case that the heat exchange has been conducted at the prescribed part, and the flow speed measurement method further includes determining a flow speed of a thermal fluid flowing inside the pipe, based on the temperature distribution measured.
